LTC5532ES6#PBF

LINEAR TECHNOLOGY  LTC5532ES6#PBF  芯片, 射频功率检测器, 0.3-7GHz

The is a 300MHz to 7GHz Precision RF Detector with gain and offset adjustment. The supply voltage range is optimized for operation from a single lithium-ion cell or 3xNiMH. The RF input voltage is peak detected using an on-chip Schottky diode. The detected voltage is buffered and supplied to the VOUT pin. The LTC5532 output buffer gain is set via external resistors. The initial starting voltage of 120mV ±35mV can be precisely adjusted using the VOS pin. The LTC5532 operates with RF input power levels from -32 to 10dBm.
